Efficient evaluation of a function at every cell of a NumPy array
...ime generated C-function as ufunc
import numba as nb
@nb.vectorize(target="cpu")
def nb_vf(x):
return x+2*x*x+4*x*x*x
It easily beats np.vectorize but also when the same function would be performed as numpy-array multiplication/addition, i.e.
# numpy-functionality
def f(x):
return x+2*x*x...

...ed design makes very few
assumptions about the target
hardware (registers, CPU features),
so it's easy to implement a VM on a
wide variety of hardware.
Since the operands for instructions
are largely implicit, the object
code will tend to be smaller. This
is important if you're going to be
